DOOR-STOP.

Specification of Letters Patent.

Patented Aug.'13, 1912.

Application filed August 10, 1911. Serial No. 643,287.

To all whom it may concern:

Be it known that LJAMES N. TATE, a citi- Zen of the United States, residing at Faribault, in the county of Rice and State of Minnesota, have invented certain new and useful Improvements in Door- Steps, of which the following is a specification.

My invention relates to improvements in door or window stops, its object being to provide a simple device which may be used to look a door or window closed or in any desired open position without injury to the surrounding framework.

To this end my invention consists in the features of construction, combination, and arrangement of parts hereinafter described and claimed.

In the accompanying drawings forming part of this specification, Figure 1 is a perspective view of my invention attached to a door and adjusted to hold the door locked in set position, the door being shown partly broken away; Fig. 2 is a side view of the same broken away; and Fig. 3 is a side view of the device closed.

Referring to the drawings A represents an ordinary swing door and 2 the floor. The stationary member 3 of my device is secured to the bottom inner face of the door as by screws 4 and is shown formed with longitudinally spaced outwardly projecting flanges 5. Between the lower ends of the flanges 5 is journaled a shaft 6 carrying a spring 7 ,the outer looped end of said spring passing through a longitudinal opening 8 in a block 9. The block 9 is tapered toward its inner end and slides upon said spring 7. Consequently with the device standing as shown in Fig. 3, the block will be held flat against the fixed member 3 by means of the spring 7, the block lying in the space between the fianges 5 and the tapered end of the block standing alongside the lower edge of the door. IVhen it is desired to lock the door in set position the block is turned downward by pressing the feet against the heel end 10 of the block and when the block is forced downward in resting position upon the floor it is shoved forwardly underneath the roller 11 carried by the shaft 6 tightly into wedging position. This will hold the door against further opening movement as any opening movement of the door will tend to increase the wedging effect of the block. The door is closed enough to carry it away from wedging position when the spring which bears upwardly against the block at its free end will be thrown up into position shown in Fig. 3.

It will be evident that I may more or less modify my invention and may adapt the same for use with either a door or window.

I claim as my invention:

1. In combination with a stationary and adjacent movable part, means for holding said movable part in set position, comprising a supporting member carried by said movable part, a wedge block and means for supporting said wedge block from said supporting member and in wedging position between said stationary and said movable part, comprising a spring supported by said supporting member and slidably engaging with said wedge block.

2. In combination with a door and adjacent stationary part, means for holding said door in set position comprising a supporting member carried by said door and projecting to the edge thereof, a wedge block formed with a longitudinal slot and a spring having journal support in the outer end of said supporting member and extending slidably through said slot for the purpose set forth.

8. In combination with a door and an adjaeent stationary part, means for holding said door in set position comprising a supporting member carried thereby and projecting to the edge thereof, a roller journaled in the outer end of said supporting member, an outwardly projecting spring journaled in connection with said roller, and a wedge block loosely slidable upon the free end of said spring for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES N. TATE.
